APPARATUS FOR ELEVATING OR DUMPING GRAIN.

SPECIFICATION forming part of Letters Patent N 0. 592,650, dated October26, 1897. Application filed July 2, 1896. Serial No. 597,852. (Nomodel.)

To all whom/it may concern.-

Be it known that I, WILLIAM F. KENDALL, a citizen of the United States,residing at Lu Verne, in the county of Rock and State of Minnesota, haveinvented certain new and useful Improvements in Apparatus for Ele-'vating or Dumping Grain; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to .which it appertains to make and use thesame.

My invention relates to improvements in apparatus for elevating anddumping grain, (to.

The invention consists of the combination with an inclined frame, anelevating-car mounted upon the same and provided with adischarge-opening, a door over said opening, traction-rollers on saiddoor, a track upon said frame upon which the rollers rest for supportingsaid door normally in a closed position, and an inclined portion oftrack for permitting the rollers to descend and the door to open.

It also consists of the combination with an inclined frame, anelevating-car mounted upon the same, a cam-brake mounted upon said carand adapted to normally engage a portion of the frame to prevent the carfrom slidingbac kward during its ascent, and a projection at the upperend of the frame for tripping the dam to throw itout of engagement withthe frame and permit the car to descend.

It also consists of certain other novel constructions, combinations, andarrangements of parts, all of which will be hereinafter moreparticularly set forth and claimed.

' In the accompanying drawings, forming part of this specification,Figure 1 represents a side elevation, partly broken away, of theapparatus embodying my invention, the car being shown in its lowerposition by dotted lines. Fig. 2 represents a transverse section throughmy said apparatus. Fig. 3 represents a bottom plan viewof mysaidapparatus. Fig. 4 represents a detail side elevation of the car atthe upper end of the inclined track with'thelocking-c'am in itsinoperative position, and Fig. 5 represents a detail perspective view ofthe detachable extension for the car-body.

A in the drawings represents the frame, which is adapted to be rested inan inclined position against the storehouse or other place where thegrain is to be deposited.

B represents the car or elevator; 13, the extension-top of the same; 0,the operatingrope, and D the storehouse.

The frame A is composed of longitudinal timbers a, a, and a arrangedside by side in a stair-step manner and secured together to form thelongitudinal sides of the frame. These longitudinal portions of theframe are secured together at intervals by cross-bars a connecting theirlower edges or rather the lower edges of the parts a and a which are onthe same level. These cross-bars act as braces to hold the frametogether and at the same time subserve the use of the frame as a ladderwhen so desired.

The car or elevator B is constructed with an inclined bottom 6, so thatwhen in position upon the frame its top edge will occupy approximately ahorizontal position. This car is provided at its front and rear endswith traction rollers or wheels Z). These wheels are loosely mountedupon axles b that are secured in brackets or extensions at the underside of the car. Suitable collars or nuts b are applied upon the axlesto prevent the wheels from moving longitudinally thereon. Thesetraction-wheels of the car are adapted to run upon the upper surface ofthe timbers a a, being guided and prevented from running off the same bythe timbers a, which project above said timbers a a;

The car B is provided in its bottom with a discharge-openin g 19 aboutwhich is provided a pendent casing 19 A door or trap b is adapted toclose over and about this casing, being hinged to the bottom of the carat its rear edge, as at 12 The door is supported in position over thedischarge-opening by traction-wheels b loosely mounted upon a shaft 6that is secured to the forward free end of the .door by suitablebrackets. These wheels 11 are adapted to rest upon the upper surfaces ofthe timbers a and thus keep the door normally closed. The timbers a?terminate a short distance from the upper end of the frame and areprovided with curved segmental castings 19 which form downwardlyinclinedcontinuations of the timbers a When the car reaches these castings, thewheels b of the door roll down the inclines and allow the door to openand the contents of the car to be discharged. As the car moves backwardagain down the incline the wheels 11 roll up the castings and close thedoor or trap again. The car is operated up and down the incline by apower-rope O. This rope is connected to. any desirable source of powerand passes over pulleys Z) b at the top of the frame and pulleys I) Dupon the car and has its opposite end secured to the top of the frame.

It is very desirable in an apparatus of this class to secure the car orelevator against rapid and destructive descent in the event of thebreakage of any of the parts or the opcrating-rope. I accomplish this bymy improved form of brake E, one of which is mounted upon each side ofthe car. Each of these brakes comprises a cam 6, provided with a milledperiphery and having an angular slot 6. Headed pins c pass through theseslots and are supported upon arms 6 projecting from the car. Braces 6also extend from the car and assist in supporting the headed pins inposition. The angular slot 0 of each cam is in such a position withinthe cam that when the headed pin is in one or the other end of the slotthe predominating weight of the opposite end will cause said oppositeend to swing down. The cam is so constructed and mounted that when itssupporting-pin is in the rear of its slot its milled periphery willengage the under side of the timber a. As the car moves up the inclinethe cams drag against said under side of the timbers a a withoutinterfering with the movement of the car; but should the car attempt tomove backward down the incline the cams would jam against the undersides of timbers a a and thus stop its descent. lVhen the car reachesthe upper end of its travel,eacl1 cam is thrown out of its operatingposition by an incline bracketf, secured to the frame so as to beengaged by the forwardly-projecting end of the cam. hen the cam strikesthis projection, its forward end rides up the incline, and upon thecontinued movement of the said cam it is forced backward upon itssupporting-pin, so that the preponderance of weight will be to the rearof the pin, and thus hold the cam in this inoperative position, with itssmooth side against the under side of the timber a. When the cams occupythis position, there is no obstacle to the descent of the car. \Vhen thecar reaches its lowermost position, the cams are returned to theiroperative positions by inclined projections f f, secured to the frame atits bottom. These projections operate in substantially the same manneras the projections at the top of the frame, pushing the cams forwarduntil the superior weight forward of the supporting-pins causes them todrop into operative position with their milled peripheries engaging theunder sides of the timbers a a. The frame A may be either set againstthe side of a granary, as shown in Fig. 2, or against the side of a carto be loaded, or, in fact, any desired position or place.

The extension-top B is rectangular in form to correspond to the shape ofthe upper edge of the car. This top is adapted to be applied to the carto increase its capacity by means of pendent arms 7L,that are adapted tolit both without and within the upper edge of the car. The top is heldfrom rising vertically by hooks 7L8, applied on the car and engagingeyes 7L secured to said top. This extensiontop is of varying depth,being deeper at one end than at the other, so that when the frame isplaced at different inclines it can be reversed to always keep the topof the car on an approximately horizontal line.

Vhen my elevator is applied to a granary, as shown in Fig. 2, thesegmental castings b are hooked over the edge of the opening in theroof, and thus when the door of the car opens the discharge is directlyin the hopper L within the granary D. From this hopper chutes t' i leadto different bins within the room and thus distribute the grain evenly.

I preferably rest the lower end of the frame in a hollow, so as to bringthe top of the car when in its lowest position at such a level that thegrain may be readily dumped into the car.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an apparatus adapted for elevating and dumping grain into a barnwithout the car passing into the barn in dumping, the combination withan inclined frame having an inner and an outer track, an elevatingcarmounted upon the same and provided with a discharge-opening in itsbottom, a door covering said opening and hinged at its lower end andfree atits upper end, traction-rollers on the free end of said door forsupporting it normally in a closed position by resting upon the inclinedtrack, and an inclined portion of the inner track at the upper end ofthe same for permitting the rollers on the door to descend thereon, asthe car travels up the incline independently of the car-bodyand withoutsaid door losing its supporting contact with the inner track, andallowing the door to open for the discharge of the contents of the car,without the body of the car descending below the inclined frame, thecombination and construction being such that the car is adapted for use011 an inclined plane and the car at all times, supported on wheelsother than those which support the door, substantially as described.
